Be it llmown that 1, @scan FroHTnNnaUM, a citizen of Brooklyn, county of Kings, State of New York, residing at 55 Humboldt street,liave invented certain new and useful improvements in Convertible Solas; and 1 do hereby declare the following to be a lull,

. clear. and exact description ot the invention,

Aia

such 'as will enable others'skilled in the artv to which it appertains to malte and use the saine.

This invention has relation to convertible solas, and has for its general object to facilitate the operation of folding and unfolding the extensible sections in the operation ot converting the device from a sofa into a bed or vice versa. And to this end the invention resides in constructing the bed frame of three sections, one of which is stationary and secured to the sofa frame, and the others of which are foldable one onto the other and onto the stationary section.

@ther objects will appear and be better understood from that embodiment of my invention ot which the following is a specification, reference being had to the accompanying drawings forming part hereof, and in which:

ligure l, is a vertical longitudinal section showing the sections of the bed frame unfolded.

Fig. 2, isa View similar to Fig. 1, but showing the sections folded.

Fig. 3, is a detail side elevation of the mechanism for locking the movable sections one to the other-When these are folded.

1n the embodiment shown the convertible sofa comprises the usual housing a and the sectional bed frame 5. rl`he bed trame b may be folded and disposed wholly within housing a in which 4position of adjustment the said frame b supports the sea-t 5. The back 6, is disposed between the complementary ends, one of which is shown and indicated byl 7, of housing af and a pivotal connection as indicated by 8, is 'provided between the back 6, and the said ends 7. The rear portion of the seat 5, intersects the arc of movement of the back 6, at a point in oblique alinement with the pivotal connection 8, so that the back 6, when inv contact with the seat 5, inclines upwardly and rearwardly and coperates with the rear cross piece 9, connecting the ends 7, to pro- '.l`he sections 11, 12, and 13l ofthe bed 4 frame 5 coperatie, vwhen unfolded, to position the usual bed spring 15, so that the sameA will support the mattress `16. A. portion of the section 11 is rigidly secured to the housing ffl and between the ends 'l thereof. 'lheb'ase'trame 17, of section 11., is herein shown as being formed of angle iron, and carries at its outer corner portions a pair of uprights, one of which is shown and indicated by 18. The side rails, one ot which is shown and indicated by 19,'ol section 12, are pivotally connected at one end to the uprights 18, and link connections, one of which is shown and indicated by 20, are

made between the adjacent ends of the side rails 19, and the side rails 21 `of section 13. Section 18 is made less in length than section 12. and the link connections 20 are so proportioned in length as to correspond approximately to twice the thickness of the mattress, so that when section 13, is folded onto sections 12, the rails 21 of the former will be parallel with the rails 19 of the latter, as shown bydotted lines in Fig. l. When' the section 18 is folded onto section 12 as just stated, uprights 22 disposed at the ends of foot rail 23 bear on the rails 19-19 of section 12. 1n this connection it may be well to state that the rails 19-19, are of angle iron and the base sides of such rails extend outwardly so as to intercept the uprights 22.

. 22 when the Sections 12 and 13 move into approximately the vertical position in the operation of folding the said sections onto section 11. This engagement between the latch bolts and the uprights has the e'ect of locking the sections 12 and 13, one to the other as these move toward section 11. rl`he latch bolts are held against detachment from the rails 19, by pins 26, which pass through slots 27 in the rails 19.

The length of section 12 is greater than the corresponding dimension of section 11, and the link connections 20 are so disposed that the ends of the rails 19 will project for an appreciable distance beyond the links when the section 13 is folded onto the section 12 so that when the said sections are folded onto the section 11, the projecting end portions, one of. which is shown in Fig. 2, and indicated by 28, will bear on the brackets 29 secured to the ends 7 ,of the housing (1.

One end of spring 15, is connected to the foot rail 23, and the opposite end of said spring is connected to a h ead rail 30. 4 A pair of arms, one of which 1s shown and 1ndicated by 31, are connected to the head rail 30 and are pivotally connected as indicated by 32, to a pair of rods, one of whlch 1s shown and indicated by 33, secured to thev uprights 18, and to uprights 34. The said uprights 34 being positioned at the rear corners of the frame 17.' l

AWhen the sections 11, 12 and 13 are folded one upon the other the head rail 3() bears on the frame 17 as shown in Fig. 2. But when the said sections are unfolded the head rail 30' is elevated into the plane of the rails 19 and 21. The elevation of the head rail 30 is caused by the movement of section 13, 1n unfolding from the position shown by dotted lines in Fig. 1. A pair of' chains, one of which is shown and indicated by 35, prevent upward movement of the head rail 30 beyond the position just stated. When the 'sections are folded one upon the other the spring 15, is relaxed. But the unfolding of section 13 operates to tension the said spring. This is because the chains 35 operate to hold the head rail 30 against upward and outward movement during the outward and downward movement necessary to adjust section 13 into horizontal alinement with section 12.

With respect to the position of the parts as illustrated in Fig. 1, it will be observed vthat the outer end portions of the rails 19 are provided `with rigidly attached supports one of which is shown and indicated by 36. 'lheends of these supports come into contact with the floor andoperate to support the section 12, when the same is unfolded, and link connections, one of which is shown and indicated by 37, extend between the lower ends of supports 36, and the supports, one of which is shown and indicated by 38, of section 13. The supports 38 are pivotally connected to the rails 21 and the links operate to fold and unfold the said supports during the folding and unfolding of section 13. When the section 13 is unfolded the links 37 bear upon the floor and coperate. with the supp'orts 36 and 38 to provide a support common to the sections 12 and 13. When the frame is folded, the links 37 are folded, as shown in Fig. 2, and project upwardly within the housing behind the back 6.

When the Aparts are arranged as shown in Fig. 2, the outer side of the seat 5, projects a trifle beyond the pivotal connection between the uprights 18` and section 12, and appears continuous or substantially so with necedad the usual covering of plush, leather or the like, which covers the space between the uprights 18.

In the act of unfolding section 12 seat 5 moves therewith and in `so moving is prevented from binding on the uprights by the presence of links 39 and 40 which connect seat 5 with the side rails 19', and which are disposed so as to cause the seat to move relatively to the section 12 during the initial turning movement thereof and nally to hold the said seat suspended and depending from the rails 19 and between the uprights 1S and supports 36 when the section 12 is unfolded.

In folding the sections 12 and 13 onto section 11, end extensions 41 of rails 19, tension spring 42 connected to the said` extensions and to section 11.A This tensioning of the ysprings 42 operates to prevent free downward and inward movement of the sections 12 and 13 as these approach section 11.

When the parts are positioned as shownin Fig. 2, the device may be converted into a bed by engaging the loop 43 of back6, and causing the said back to move upwardl 'and outwardly until latch bars, one of which is shown and indicated by 44, engage with keepers 45. In this position of adjustment of the back suiicient space is afforded to permit the operator, on taking hold of a convenient portion of section 12, to unfold the same and section 13 to the osition shown by dotted lines in Fig. 1. hen the parts are in the last named positions the operator proceeds to disengage the latches 24 from the section 13, after which the said section may be unfolded as previously described and as shown by full lines in Fig. 1. In converting the device into a sofa sections 12 and 13 are folded onto section 11. When the parts are so folded pocket 10 accommo` dates supports 36 and links 37. The back 6, is then permitted to descend after disengaging latch bars 44 from keepers 45.
